Buzz Aldrin Portal to Science and Space Exploration

His $2 app is a grab bag of all things space; it has writings by Buzz's, including his take on the ISS, the future of manned spaceflight, exploring Mars, etc. It also has plenty of YouTube clips, including one from 2009 in which Buzz talks about the monolith on Mars' moon and others in which he talks about his time on Dancing with the Stars.

One of those two things really fascinated me.

Muziic

Muziic: The internet has a ton of music — be it on YouTube, internet radio, or the next thing — but it's a vast, untamed wilderness.

Muziic, a free app, looks to harness all that crazy content. You can listen in on a variety of internet radio stations, create playlists of songs from YouTube, or check out featured tracks. Rock ON.

Waterprint

Gizmodo

Waterprint: "You've heard of carbon footprints," this app asserts, "but what about water footprints?"

What about water footprints?

Basically, if worrying about depleting Earth's fossil fuels wasn't enough for you, Waterprint will let you shift your concern to another precious natural resource, helping you calculate how much water you use in your daily activities. For example, thanks to Waterprint, I now know that the single cup of coffee I just consumed took 30 gallons of water to produce. Wow! Thankfully the app is free, so my newfound coffee guilt didn't cost a thing.

FoodEssentials Scanner

Everyone eats, but only some people care about what's in what they eat.

For $5, FoodEssentials Scanner will scan bar codes and give you the whole scoop, including the regular nutritional information as well as additives and allergens the item contains (important information some other similar apps leave out.)

You can also set up custom labels to restrict the information you want from your scans. Trust me, there's nothing more frustrating than getting bombarded with gluten content when you just wanna get the calorie count.

Digg

Upon firing it up you get a nice list of all the top stories, sorted by digg count, which you can preview, dive into, or save for later perusal. Of course, a Digg app would be nothing without being able to actually digg (and bury) stuff, and you can do it at pretty much every turn here.

There's something satisfying about giving a story you like a boost with your finger, as opposed to a disembodied cursor. You probably never knew you wanted a more intimate relationship with Digg, but this app gives it to you nonetheless.

Free

MacJournal

Gizmodo

MacJournal: Everyone has their own way of keeping notes, but if yours happens to be MacJournal — a fine application that was included in the most recent MacHeist Bundle — then you're in luck.

The $5 MacJournal app is pretty bare bones compared to some of the other, more established note-gathering apps, but if you're already a user of the excellent OSX MacJournal application, then you'll be happy to finally have journal syncage in your life.

Star Wars Cantina

Gizmodo

Star Wars Cantina: Kat summed up the appeal for the upcoming Star Wars Cantina game nicely: "Like Animal Crossing, but with Star Wars! and booze!"
